Might get better help if we knew what you are working on. Model and year

No matter what car it is, the brake lights and reverse lights are almost ALWAYS a seperate fuse form the tail lights.

Check the fuse and the fuse holder (clips) If the front parking lights work and the rears don't, then a bad connection is most likely the culprite.

Start with the connections at the rear (usually a bad ground)

Then move to the upper right hand (passenger side) kick panel. All your tail light connections go from there to the back.

On early Z's, the wires are red/black (for reverse) Green (for brakes) green/white (for parking lights) and black (for ground)

OH YA!! and I totally forgot about your combo-switch (headlights, parking lights and washer motor) check for output from the switch and input from the fuse box.

Those wires are as follows (on early Z's)........ on the 6-pin plug that goes to the headlights,

the input wire from the fusebox is green/blue (into the 6-pin plug) then greenwhite into the switch.

the output wire (to the parking lights) is (from the switch) green/blue then turns into a green/white on the other side of the 6-pin plug

Hope some of this helps,

Dave.
